they do not pay their promoters

my two teenage daughters did some street promotion work for this company to earn some holiday money. they were promised to be paid the Monday following the Saturday that they worked. that was more than a month ago. they still havent been paid and when i do get hold of Vicki on the phone, she gives some bull story about their server being struck by lightning and they couldnt make the payment. i got hold of the company that the girls did the actual promo for, and the owner there is just as disgusted as i am with the way these people do business. my girls will NEVER work for them again.
